Okay Jim, I guess I can understand that logic.
In days of yore (say, 10 years ago).. the peak power in a SG TC (say,
discharging several tens of joules at 30kV) was higher than you'd get
in a SSTC (because the pass devices can't take the peak current).
That was moons ago prior to decently sized DRSSTC's. Even my own DRSSTC
which is an 8.5" diameter coil is limited to 1000Apk. Bigger DRSSTC's
can do far greater than that. I know of one being limited to 3kA. When I
use the term limited, I'm referring to the OCD setting which prevents
the IGBT's from seeing anything higher than the OCD value.
Take care,
Bart
